By the 23rd century, humankind hasn’t just found aliens — we’re at war with them. That is the future presented in the 1997 film Starship Troopers, a militaristic satire that throws viewers into battle appropriate from the start off.
It is humans versus giant, plasma-slinging bugs in an interstellar war with no finish in sight. The bug’s dwelling planet, referred to as Klendathu, is situated on the opposite side of the Milky Way, however they nevertheless uncover a way to launch projectiles tens of thousands of light years away.

“Klendathu, supply of the bug meteor attacks, orbits a twin star technique whose brutal gravitational forces create an limitless provide of bug meteorites,” an unnamed voice announces throughout a military PSA inside the initial handful of minutes of the film.
Though it is by no means totally explained how the bugs handle to turn asteroids into projectiles, it is clear that they present an existential threat to humanity. In one particular scene, a bug meteor destroys Buenos Aires, wiping the city clean off the map. And in a further, starship captains have to dodge a sudden asteroid that spontaneously seems in their path, threatening to down the vessel.
What ever the bugs are carrying out, they make it appear pretty uncomplicated to wield asteroids as weapons. But in reality, moving rocks in space is a monumental job. Handily aiming and redirecting an asteroid to shove it off its orbit is a lot tougher than Starship Troopers tends to make it appear, thanks to the laws of the universe — and the limitations of 21st-century technologies.
The only time humanity ever effectively moved an asteroid was on September 26, 2022. NASA’s Double Asteroid Redirection Test (DART) took aim at the nearby asteroid Dimorphos in an try to alter its orbit.
Dimorphos orbits a bigger asteroid, Didymos — neither of which pose an active threat to Earth. The DART test was just a test, created to establish if it was feasible to redirect an asteroid in the occasion that one particular does come hurtling toward our planet in the future.

Positive sufficient, the test worked. Scientists crashed a rapid-moving, refrigerator-sized automobile into Dimorphos, then watched to see its trajectory shift in the coming weeks. The asteroid’s orbit shortened from 11 days and 55 minutes to 11 days and 23 minutes.
That may possibly not sound like significantly, but the DART test truly exceeded scientists’ expectations. If the only issue affecting Dimorphos’ orbit was the DART automobile, it would have changed its orbit a minimum of seven minutes, Cristina Thomas, an associate professor of astronomy at Northern Arizona University, told Inverse earlier this year. As an alternative, several forces acted collectively to transform the asteroid’s orbit by a lot more than a half hour.
To be fair, humanity is only in the starting stages of finding out how to shake up an asteroid’s orbit — but the DART mission shows just how hard it is to even make a slight transform in trajectory.
Asteroids are somewhat tiny pieces of matter, and are usually bound by gravity to bigger bodies such as the Sun, planets, or bigger asteroids. That tends to make them hard to disrupt, even though collisions amongst asteroids and planets with sufficient force can send bits of rock flying on a new trajectory by means of space.
The vast majority of meteorites that land on Earth come from asteroids in the Asteroid Belt, which is situated amongst Mars and Jupiter. And when asteroids, comets, and other cosmic objects can make their way into the Solar Technique from outdoors of it, these occurrences are significantly rarer.

If an asteroid came flying from the total opposite side of the Milky Way and was in a position to travel by numerous star systems with no becoming roped into the gravity of any huge bodies, then it could make it to Earth like the ones in Starship Troopers. But the bugs on Klendathu would have to launch a rock at least tens of thousands of years in advance in order to hit Earth throughout the time the film requires location.
The Milky Way is one hundred,000 light years across, and Klendathu seems to be on roughly the opposite edge of it from Earth (give or take 20,000 light years). Even if a bug asteroid was traveling at the speed of light, it’d take tens of thousands of years to get to our planet, which is not precisely the most successful technique in time of war.
Maybe there have been wormholes or other shortcuts that the bugs applied — even though the film is scant on the information. But merely pushing on an asteroid wouldn’t necessarily turn it into a space projectile. At most, you may possibly just give it a slight transform in orbit.
